ABSTRACT: The present work intends to study the
properties of magnesia based refractory aggregates developed from Indian magnesite
by changing lime/silica ratio. The material has been sintered in the
temperature range of 1550C - 1700C. The sintered samples are characterized in
terms of bulk density, apparent porosity, true density, percentage
densification, mechanical, thermo-mechanical properties like cold modulus of
rupture, hot modulus of rupture and thermal shock resistance and structural
properties by XRD. The developed microstructures at different temperatures are
studied through FESEM study and compositional analysis of the developed phases is
done by EDX study.
